1. What is the Dilution Formula?

The dilution formula \( C_f = C_i \times \frac{V_i}{V_f} \) calculates the final concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant during dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_f \) — Final concentration (M)
• \( C_i \) — Initial concentration (M)
• \( V_i \) — Initial volume (L)
• \( V_f \) — Final volume (L)

Explanation: The formula demonstrates that the final concentration is proportional to the ratio of initial to final volumes, maintaining the same amount of solute.

3. Importance of Dilution Calculation

Details: Accurate dilution calculations are essential in chemistry laboratories for preparing solutions of specific concentrations, ensuring experimental accuracy, and maintaining proper chemical ratios.

4. Using the Calculator

Tips: Enter initial concentration in M (molarity), initial volume in L, and final volume in L. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can this formula be used for both acids and bases?
A: Yes, the dilution formula applies to both acidic and basic solutions as it's based on the conservation of solute amount.

Q2: What units should I use for volume?
A: While liters (L) are used here, any consistent volume unit can be used (mL, L, etc.) as long as both Vi and Vf use the same unit.

Q3: Does temperature affect dilution calculations?
A: Temperature can affect volume measurements due to thermal expansion, but the formula itself is temperature-independent for ideal solutions.

Q4: Can I use this for serial dilutions?
A: Yes, though for serial dilutions you would need to apply the formula sequentially for each dilution step.

Q5: What if my final volume is less than initial volume?
A: This would represent concentration rather than dilution, and the formula would still apply mathematically, though physically this typically requires evaporation or other concentration methods.
